NHRA rod and head cc info

[Stewart Way]

Anyone know why NHRA has removed the latest Head cc numbers page and replacement rod page? The latest head cc page is now 1/21/09 and the latest rod page is 1/15/09/ I know there were newer pages but I can't find them now. Both those pages containing the Chally Drag Pak info are gone.

Stewart, what you are looking for is in a new location. Go to Competition on the first page of the NHRA site, from there click on NHRA Accepted Products, on that list is SS Head volumes, click on that and page to about page 56 or so. The new hemi is listed there as 191 intake and 60 exhaust. The 360 is not yet listed, but is being pored this week to get this figure. Hope that helps.

Thanks for steering me in the right direction. I was going to NHRA, then Competition on the bottom of the page, then to replacement rod section and SS runner volumes and the info wasn't there. Guess they don't update that section anymore. Maybe I am as slow a Warren tells me I am.
Thanks
